The eccentricities of planets belonging to the solar system are rather small, while a significant fraction of the discovered exoplanets exhibit large eccentricities, in excess of 0.3. Fig. 1 Several examples of elliptical orbits with different eccentricities See Also Exoplanet, Detection and ...
Eccentricity is a measure of how an orbit deviates from circular. A perfectly circular orbit has an eccentricity of zero; higher numbers indicate more elliptical orbits. Neptune, Venus, and Earth are the planets in our solar system with the least eccentric orbits. Pluto and Mercury are the ...
2d) by a temporary weakening of the AMOC. Chaotic orbital transition at ~56 Ma The orbits of planets in the Solar System are not stable (chaotic) at timescales of tens to hundreds of Myr48,53. The chaotic diffusion in the Solar System hampers the establishment of precise astronomical ...
The discovery of extrasolar planets located in the vicinity of mean-motion commensurabilities has opened a new arena for the study of resonance capture and its possible role in the dynamical evolution and long-term stability of planetary systems. Contrary to our own Solar System, many of these ...

High-inclination planets and asteroids in multistellar systems The Kozai mechanism often destabilizes high-inclination orbits. It couples changes in the eccentricity and inclination, and drives high inclination, circul... PE Verrier,NW Evans - 《Monthly Notices of the Royal Astronomical Society》 被...

solar system: formationstars: individual (OGLE-06-109LRecent observation of the microlensing technique reveals two giant planets at 2.3 AU and 4.6 AU around the star OGLE-06-109L. The eccentricity of the outer planet (e) is estimated to be 0.11, comparable to that of Saturn (0.01-0.09)....
